Complex groundwater flow systems as traveling agent models [PDF]

open access: yesPeerJ, 2014
Analyzing field data from pumping tests, we show that as with many other natural phenomena, groundwater flow exhibits complex dynamics described by 1/f power spectrum. This result is theoretically studied within an agent perspective.

Flow and Storage in Groundwater Systems [PDF]

open access: yesScience, 2002
The dynamic nature of groundwater is not readily apparent, except where discharge is focused at springs or where recharge enters sinkholes. Yet groundwater flow and storage are continually changing in response to human and climatic stresses. Wise development of groundwater resources requires a more complete understanding of these changes in flow and ...
